1 VJ-1638UH - use of customized jigs for recto/verso printing on precut blanks Mutoh Europe nv Rev /2018.

2 1638UH In this document, a semi-productive workflow is described for printing pre-cut rigids by means of customized jigs on Mutoh s ValueJet 1338UH. Watch movie at Advantages/opportunities: Increases overall production yield compared to per rigid production Facilitates edge-to-edge printing Recto-verso printing possible Roll printer users frequently making small series of sign boards will no longer have to individually trim and stick roll prints to individual sign boards As examples, following two jigs are presented : JIG N 1 A4_A5 jig : Yield 10 x A x A5 mix Page 2 of 13

3 JIG N 2 A6 jig : Yield 70 x A6 Page 3 of 13

5 1. Designing Your Jig Example : A4_A5 jig On VJ-1638UH, each pinch roll can be individually enabled/disabled; This way, you can distribute samples over the jig s surface while still maintaining enough pinch rolls to accurately feed forward during printing and have sufficient grip on the jig itself. Take into account standard print margins : Left-right : 5 mm Front : 5 mm (non-layered) ; 30 mm (layered) Rear : 40 mm The red rectangle represents the actual cutting line, the black rectangle is the image area taking into account a bleed of 5 mm.

9 In case of A6 jig : Example: a6 recto.pdf Page 9 of 13

10 4. SAi / Onyx RIP Settings SAi Resolution : 720 x 1080 dpi unidir ; speed = 3.4 sqm/h Set media size to jig dimensions; set page margins to 0 ONYX Resolution : 720 x 1080 dpi unidir ; speed = 3.4 sqm/h Select 64 inch roll media size Page 10 of 13

11 5. How to Load the Jig In the RIP software, you can change the positioning of the image on the media via X- and Y-offset. SAi Example : Y-offset = 5mm ; X-offset = 10 mm ONYX Example : Y-offset = 1.0 mm; X-offset = 9.0 mm When using roll to roll media, the X-offset is not crucial, except for possible top feed when using platen heaters. When using a jig, however, the X-offset is as important as the Y- offset for correct placement of print data. Every time the jig is manually loaded, after media initial phase (height, top&width) is finished and before starting to print, the actual start position of the jig in X-direction must be the same. In case of A6 jig, do lever down when jig is physically in position as shown in the picture below. Page 11 of 13

12 Warning : During media initial phase, please make sure to set the total head height ( actual thickness + offset) to maximum Remark : The detected media width can be verified and is shown on the panel, in case of both jigs this value should be > 1400 mm Page 12 of 13

13 6. Finding correct X and Y-offset values In case of A6 jig, print file a6 pos.pdf This will print 2 black positioning marks. With the correct X- and Y-offset applied, the positioning marks should be as shown in the picture below Once the positioning marks are in the right place, you are all set to print both recto and verso image files.
